The (neutralizer and softener) systems are working great. – Testimonial

We don't have any questions at this time.  The systems are working great. The only thing is that when I ordered the water softener you said that you would send a hard water test kit–we didn't receive it with the order. 🙂 Thank you, Terri & Paul Knoke
